Pain, love; hurt...
There will always be one person who will be lonely, stumbling, and grudges from life to life...
Why is this so? Right or wrong is just a matter of what you believe at the time...
Without love, why complain? No resentment; where can I think about it? If you don't think about it, how can you regret it? No regrets; how could it be hurt?
No regrets... It's so difficult, you can see how far it is...
